Ode Chem LLP manufactures high-purity Di Sodium Phosphate (DSP) Dihydrate. This crystalline form is an excellent alkaline buffer and stabilizer. Its primary advantage over the anhydrous form is its physical stability; the dihydrate crystals are resistant to caking and moisture absorption from the atmosphere. This makes it the "gold standard" for precise laboratory work and sensitive pharmaceutical applications.

Applications
A key component in the preparation of Phosphate Buffered Saline (PBS) and mobile phases for HPLC (High-Performance Liquid Chromatography).
Used as a stabilizer and pH regulator in specialized dairy products, ensuring the solubility of milk proteins during heat treatment.
Widely used as a buffering agent in injectable and ophthalmic (eye drop) formulations to maintain a stable pH near physiological levels.
Provides superior alkalinity control in high-pressure boiler systems where precise dosing is required.
Acts as a leveling agent in dyeing processes to ensure even color distribution on fabrics.
The Dihydrate contains two water molecules, making it more stable and less prone to caking than the Anhydrous version.
Yes, our Reagent Grade is specifically manufactured for analytical laboratory use with ultra-low impurity levels.
The specific CAS number is 10028-24-7.
